BooKBINDrNc-MACHINE.

.To4 all whom 'it may concern:

Be it known that I., .JOHN MURRAY, a subject of the King 'of Great Britain', `,and

"resident .of Parkside Works, Dalkeith Road, y

Edinburgh, Scotland, engineer, have in vented new and .useful mprovements in BookbindingrMachines, of which the following is a specification.

The present invention has tor its object a novel construction of machine for carrying out the operation known as lining in the trade of book-binding.

The machine is designed' to be used in conjunction with a roundin machine and will preteraolyl e driven from lthe shaft of the latter but it is also capable of bei-ng' used independently.

The operation' termed lining in the trade of-book-binding consists in Athe application of a coating oit-glue .or `similar' .adhesive .to the backof the book, which .uni-tes the sections of the book and provides an adhe'sive snrface to which 'the reinforcing or lining material, such as -scrim or paper, is applied, so that the back of the book has the'cohesion necessary to resist the strain of' frequent opening and closing.

, The invention consists mainly in an imi proved meansl tor holding :and applyin the lining material to the glued backs `o the books and for severing .the same :from :the

roll at the proper moment:

The invention com/prises also means for controlling the oper'ationof the lining mechanism so as to render them inoperative in case .of accident-al stoppage of the feed of books'into the machine.

Similar lettersrefer to like parts in the several :figures 1' a is a horizontal table supported on suitable standards such as b; Supported by 'table a, on brackets c, are a pair of parallel horizontal guide rails d cl. Fitted 1n a re- ,cess at .each'end of one rail d, `are chain or sprocket wheels e\ which drive the chain f along grooves in the face of said rail. Attached to the chain f and extending across the space' ibetween the rails2 which is variable, into a corresponding groove in the rail opposite, are pms g. 4An intermittent motion is transmitted to'one of the chain wheels e from .the cam shaft k through bevel wheels j, crank lo, .rack m, ratchet n and gear wheels 0.. When the chain with its pins is at rest, a .book is inserted between the rails d d Where .it is supported on its fore-edge on .rails or suspended by .its joints on rails r. T e next forward move. men-t` of the pins will cause' the book to move torward .and present its back succes. sively to the mechanical devices hereinafter to be described. The space between the rails is vmade variable as follows. Referring to Figs. 1 and 2, the brackets c whichv .carry the rails d have beneath them lugs c c through which shafts d d pass provided with right and left handedl screws e e. The shafts .are furnished with worm wheels f ff and engaging with these worm wheels are worms g', g', 4carried on a shaft k extending' the -whole lengthef the machine. If this 'shaft be turned by means of the lhand wheel z" shown, the bracket c and the railsl al carried thereby may be movedin and outland the space betweenL the rails adjusted to anyfde'sired width. Referring to Fig. 3,

a book is inserted at and the vnext movement of the chain and pins conveysit to Z and then to s, where the back of the book is coated with lue. t is the drying position.

- At u the scrim is out from an endless web and-'attached to the` now adhesive back of the book, as shown in Fig. 4. During the movements between positions u and o, the

pendent ends of thescrim are folded closely into thesides of the book as shown in Figs.

5 and 6, by the inclined bars w and a1. At. y,

the book is again coated with glue and moved through theposition a to Z, where the paper lining is also cut from an -endless web and att-ached to the bookl and pressed firmly so that complete contact is assured. The op 'erations are now complete and the book is discharged from the machine.

The mechanism forv gluing the book and applying the lining will nowfbe more fully described.

lF ig. 7 is a cross section of the machine through position s of Fig. 3. 2 is a gluing cylinder revolved in the glue tank 3 by chain gear 4 which is driven from the cam shaft L. 5 is an intermediate glue roll ad;

, justable in relationfto the gluing cylinder 2, by means of eccentric bearingv 6.' The 36 quantity of glue transferred to the vibrating roll 7 isthus regulated. The vibrating roll 7 which transfers the glue .to theback ofthe book is carried on a pair of jointed vibrating arms 8 rocked by the cam 9 and has a motion'of rotation transmitted by a train of smallgears on the said vibrating arms 8 driven by teeth on .the periphery of the said cam 9. The oll7 during its vibration, transfers a po tion of the glue onl 40 its Surface to the back ofthe book. The remainder of the glue which will be slightly chilled, is removed by scraper 10 and returned to the` glue tank byl the inclined i guide 11. The glue roll 7 is supported duringjits' movement, on the cam-shaped guides Fig. 8 which is across section of the machine through position u, shows the means by whichy the attachment of the scrim is accomplished. Figs. 9,'13'and 14 also illustrate the-operations on the scrim. 13 is a roll of-scrim supported in bearings 14, (see` Fig. 8), and controlled by friction sides 15. The -web is led intoy the .feed rolls 16 over guide rods '17. From thefeed rolls'l the `scrim is drawn on to the back ofthe book by rods 18, 19, 20' and,` 21, see Figs. 8, 9, 13

and 14, without any of the working parts coming into contact with the adhesive. This is very desirable asit enables the machine to. continue its Work without stoppage for cleaning as would be otherwise necessary.y The rods 18 and 19 are supported at their ends by'inverted U-shaped brackets 22, sup'- ported on and actuated by rods 23, see Figs.

Vrollbearing on a camon the shaft h, (sce on the sides of the rods 23 which mesh with 'I and before either end of the scrim is re- Sja-nd 13. The said rods 23 are connected together by a cross headl clearly seen in Fig. 13, which cross' headis moved up and down by a link mechanism operated by a Fig. 8). Therods 20, 21, are supported by vU-shaped brackets 24 and their stems 25 are guided in brackets 26 and maintained by their springs 27 in their full-.up position. The supports of the rods 2O and 21 have no positive motion of their own but are movable in 'a downward direction vby the pressure of the rods 18 .and 19 and in the opposite direction by means of the springs 27. Further, sliding in brackets 28, is a hollow sheet metal guide 29 which has a to and vfr'o motion impartedl to it bythe lever 63 r' which rocks on a fulcrum 64 on the framing a and carries a roll 65 working in a suitably grooved cam 66 on the shaft L. The cycle o f'themovements in the operation is as follows: The rods 18, 19, retire to their fullup position but the `rods 20 and21 cannotvl follow under the influence of their springs, because they are stopped by shoulders on their stems 25 before 18 and 19 have reached their full-up position.v The pairs of rods arethus separated as shown in Fig. 8, thus lleaving sufficient space between them so that the guide 29 can pass through. 'As the scrim is very flimsy, it would not with certainty support itself. across the space between the two pairs of rods and to insure positive working the guide 29 advances with its open mouth between the rods right up to the opening 100 through which the scrim is ejected by the feed rolls 16.V Thescrim is thus passed into guide 29 whichthen retires, leaving the scrim safely between the rods. The rods 18 and 19 now descend and'grip the scrim, and as it is thus securely held it is cut from the web bythe shear blades 30. By a posiy tive downward movement of the rods 18, 19, pressing o'n the rods 20, 21, thescrim which .is now held between them is drawn down onto 4the adhesive on theback of the book. As it would be;l difficult to insure a simultaneous release of the-ends of the scrim if the rods were permitted to draw clear olf `and asa failure of simultaneous release might cause the scrim to. be displaced tol one side or the other,means are provided for separating the rods before the scrim has slipped from between-them. Teeth are cut -pinions 31,1see Figs. 8 and 13 and the de-' ,y

"tached view Fig. 17. 'The'downward movement 'of-rods 23 will thus rotate the small overhung arms 3-2 at each side' of the scrim device (see Fig. '13). Projecting across the path of the arms 32 are pins 33 fixed in qthe side of rods 20, 21.' As the rods 18, 19, ,i

2O and 21 approach the end of their stroke leeedf the amS 32 will act on the pins sa 130 and depress the rods 20 and 21 to the position of Fig. 14' and release both ends of the scrim simultaneously. As the operator might miss feeding a book, means are provided to automatically prevent the feeding of scrim orV paper lining material if a book is not' present to receive it. Swinging on the vertical shaft 34, see Figs. 15 and 16, is an arm 35 the endv 36 of which yprojects through a slot in one of the guide rails d. On the end of the arm 35, sector teeth are formed gearing with a pinion 37 which transmits the .motion of the arm 35 to the shaft 38 through segmental bevel wheels 39. Attached to the shaft 38 is an arm 40 carrying teeth which engage with pinion 41 concentric with the feed roll 16 and fixed to a disk 42 with a cam shaped lip which trips the pawl of the feeding mechanism if no book is in the machine against the arm 40. As the book enters positions u and z itV presses back the end of the arm 35 and thus by -means of the combination just described, releases the feed pawl so that it engages Vthe ratchet wheel and allows the feeding of the scrim or paper to proceed. As the book moves away, the arm 40 is 'returned to its idle position by a spring and its return againI puts the feeding mechanism out of action. v

The device for feeding and attaching the paper lining is shown at Fig. 10 and is very similar to that for feeding the scrim and similarvsymbols of reference are used when applicable in both cases, but to assure a close union between the book back and the paper lining, the paper is damped by causing it to pass through a water duct 60, ther surplus water being removed by causing the 4web to pass between absorbent rollers 43 of felt or other material. In Fig. 3, the roll of lining paper is indicated by 13 and the bearings whieh-support it by 14, 14. Further, as the paper has no overhanging ends like the scrim, the paper is conveyed to the back of the book `by a, gripper as shown in Figs. 11, 18 -and 19. Suspended from a pair of brackets 44, see Figs. 11 and 23, is a hollow compression pad 56 of india rubber. The said brackets are carried on apair of slide rods 45 see Figs. 10 and 11 attached to cross head 57 and moved in a vertical direction by vthrough which 'the feeding connecting rod 46 and lever 47 in a manner similar to the construction shown in Fig. 13 in connection with another part of the machine. The gripper 48 is supported by shaft 49 attached to the sliding plate 50-which is moved in a horizontal direction by means clearly shown in the drawing, (see Fig. 10.) Attached to bracket 44 are studs 51 and 52 which operate the gripper in the following manner: The gripper advances to the slit 53 mechanism will eject the end of the paper. The gripper is opened to receive the paper "by stud 51, see

gripper.

Fig. 19, acting on arm 58 on the upper jaw of the gripper 48 by a downward movement of rod 45. The paper is fed out, the outer end of the strip being delivered into the gripper. Rod 45 then rises and the gripper being released by the overlying stud 51 is closed bythe springs 62. The paper is now cut by the shear 55. The gripper then retires to position shown in Fi 10, where another downward movement of rod 45 causes stud -61 to press on the projection 63 on the lower jaw of the gripper thereby rotating the gripper into the position as shown in Fig. 11. The paper is now laid in position on the back of the book when rod 45 again moves down and opens the gripper by means of the stud 52 acting on the arm 58 of the upper jaw of the position and is brought back to the horizontal position bymeansv of spring 59. The rod 45 now brings down the hollow pad 56 and presses the paper firmly on to the book as shown in Fig. 12. It may be remarked that where the paper lining is not used the machine may be constructed without the paper lininof appliances above described.
